Israel-Gaza live updates: Sirens sound in Tel Aviv as Hamas fires rocket from Gaza

Israel launched a preemptive strike on Hezbollah in Lebanon, Israel Defense Forces spokesman Daniel Hagari said in a video on X.

"A short while ago, the IDF identified the Hezbollah terrorist organization preparing to fire missiles and rockets toward Israeli territory," Hagari said.

"In a self-defense act to remove these threats, the IDF is striking terror targets in Lebanon, from which Hezbollah was planning to launch their attacks on Israeli civilians," Hagari continued.

Hamas will not take part in the cease-fire talks scheduled for Sunday, an Egyptian official told ABC News.

U.S., Israeli and Qatari delegations will take part, the source said.

A Hamas delegation traveled to Cairo on Saturday to hear the details of the latest proposal from the mediators, but they will not participate in the talks themselves, Sunday, according to the source.

The Houthis released videos on Saturday showing an explosion on a Sounion oil taker and a massive fire on the ship which was reportedly attacked while moving across the Red Sea early Wednesday, according to the Hellenic Maritime and UK Maritime Trade Operations, UKMTO.

According to authorities, the vessel was first damaged following a gunfire attack from two small boats and a small missile attack early on Wednesday, approximately 72 nautical miles from Hodeida, Yemen, while it was sailing from Iraq to Agioi Theodoroi, Greece.

After the attack, the crew safely evacuated the vessel and left it anchored off the Yemeni coast. UKMTO reported multiple fires on the oil tanker on Friday, as engine damage left the boat adrift.

An airstrike on western Khan Younis, inside the Israeli designated safe zone, killed 11 people including two children, according to Nasser Hospital.

The safe zone now consists of just 15.8 square miles where over 1 million people are sheltering.
